bump test coverage, minor version, controller renderers, better fork flow

* refactor forking for dev (and debugger) to use kona bin and parse args
* lots of unit test coverage for kona, base controller, some support
* cleanup some unused functions
* delegate resp of assigning req, res, etc to controller constructor
* add winston logger to write to env log
* add lodash and underscore.inflections and expose on Kona global
* make controller#render non-generator since the renderer middleware will handle that
* add Hashjs for params object usage and traversal
